Hi Eric,
whoops maybe I better read my earlier post, just in case I gave a wrong impression. The sd2 is only a a tiny pocket size soundmodule , it doesn't have styles.

Where it's handy for me is for user styles or converted styles that require editing /tweaking especially where drums are concerned. When I get my sd drum library built up I'll just be able to replace the existing drum track with one from my library. ( Using OMB software)

I wouldn't waste my time tweaking internal styles to hear them played back using sd2 sounds. The psr drums wouldn't play back correctly anyway.
&
unfortunately as far as psr's go, the midi's not great.
Using OMB as the "arranger", I can assign multiple soundsources ,
but using it with a psr keyboard, the sd2 has to be the soundsource for all 8 style tracks. Only left & right hand voices can be set to psr internal voices.

best wishes
Rikki
